OK. I see your point. I am wondering about the practical aspects. A number of you fellows carried firearms every day for years. It may be a lot simpler than I imagine but I am remembering how hot it was in my classroom, Fall-winter-spring in the 80s on average. Not gonna wear a jacket. Is it as simple as not tucking in my shirt and wearing a holster tucked behind the waistband?
I am aware that the question may sound silly to people with vast experience. To someone new to the experience, however, it may not be so simple.
I expect that the idea would be well explained in training classes before a person was permitted to carry in a school.
Note: I own quite a few firearms. I load ammo for all of them and shoot regularly. Living in NYC, however, I never carried. In PA after I retired, yes but that is an entirely different scenario.
